His current club Pachuca held a meeting with the player and his parents on Monday to agree arrangements, with the youngster reportedly due on Merseyside sometime between August 10 and 12 to begin training with the reserves.
"A pre-contract with the parents and Bueno was signed to be sent to Liverpool," vice-president Andres Fassi told El Universal.
"So we are accepting the 10-day trial and the conditions, if the English decide to keep him."
Bueno, talking about the prospective move to England, told record.com: "I have to face it with great motivation and commitment to represent the country in the best way, and with faith that everything is achievable."
Asked about having the chance of playing alongside some of Liverpool's stars he added: "Yes, I really do want that.
"It's a life experience that I will never forget, I'm very excited about that and will give my best.
"Where the opportunity arises I will make the most."
Reports in the Spanish media also claim Liverpool have secured a deal for Albacete youngster Nacho, who had a successful trial with the club's under-18s earlier this month.
The Spanish press say the Reds have paid £150,000 up front for the striker with a further £350,000 of potential add-ons, plus a 15 per cent sell-on fee.
Villarreal, Atletico Madrid, Real Madrid and Malaga were all reportedly interested in the player.
